WAGON PLATFORM-GEAR.

Specification of Letters Patent.

Patented Aug. 28, 1906.

Application filed January 5, 1906. 7 Serial No. 294,737.

To all whom it may concern:

Be it known that I, WILLIAM F. HINDE- NACH, a citizen of'the UnitedStates, residing at Marshall, in the county of Calhoun and State ofMichigan, have invented certain new and useful Improvements inWagonPlatform- Gears; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to wagon platformgearing; and the chief object ofthe same is to provide such gearing in which the truss-rods arepositively locked to the head-block and to facilitate the regulating ofthe tension at will.

To these ends my invention consists in the construction and combinationof parts hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1 is a top plan view of a wagonplatform-gearing embodying my invention. Fig. 2, is a side elevation ofthe same. Fig. 3 is a plan view of my truss-rods. Fig. 4 is an end viewof said platform-gearing. Figs. 5 and 6 are detail views of thehead-block.

A designates the center bar of my platform-gearing; B B, the outsidebars or futchells; C, the front cross-bar, secured to the front ends ofthe futchells and the center bar; D, the center cross-bar, secured tothe under sides of the futchells and center bar at about their middle,and E the circle-bar supported by the center bar and center cross-b ar.

F designates my new and improved headblock, preferably cast in a singlepiece, adapted to receive the rear ends of the center bar, thefutchells, and the truss-rods. Said headblock is provided with a topplate f, side plates f, back plate f bottom plate f and cleats f saidcleats being in the same plane as the said bottom plate, but placed atthe front ends of side plates f. These plates and cleats partiallyinclose a rearwardly-converging quadrilateral space which receives therear ends of the center bar A and the futchells B B and holds the sametogether. To increase the efficiency of this part of the head-block,bolts n are passed through holes n in the top plate and cleats and inthe top plate and bottom plate and positively lock rods, and with alongitudinal tapering groove X leading to the same.

My truss-rods G G are of a new and improved construction especiallyadapted to be used with the above-described head-block.

and form a rod X, the screw-threaded end of which passes through thehead-block and is held by a nut r, bearing against the back plate of thesame. From their said point of union the truss-rods are carrieddivergingly forward beneath the center cross-bar D, and their forwardends are fastened in any convenient manner to the front cross-bar C.

By means of the above-described trussbars and head-block my device notonly holds the rear ends of the futchells and center bar together, aswell as the common rear end of the truss-rods, but provides means foradjusting the tension-of the latter at will, said means being the nut:20, bearing on the back plate of the head-block.

The form of futchells, center bar, front cross-bar, center cross-bar,and circle-bar as a frame for this kind of a gearing is old. Myimprovement lies in my novel construction of the head-block andtruss-rods whereby the whole frame is closely united, and the tension ofthe truss-rods may be increased or decreased by turning but one nut.Heretofore it has been necessary to tighten or loosen at least two nuts,one on the end of each trussrod. Usually the truss rods have been boltedto the frame at the rear end; but this weakens them by removing part oftheir material. To obviate this weakening, others have sought to use asingle truss-rod bent around a projectionon top of the headblock; butsuch a construction does not securely hold the loop or bend at the rearend and is necessarily difficult to adjust or to remove. My constructionholds the truss-rods positively locked and admits of instant detach mentat will by unscrewing the nut 00.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1; In a wagon platform-gearing a metallic head-block in combination witha rod formed by the union of two converging truss-rods near the rear ofsaid platform and in proximity to said head-block, passing through thesame and adapted to be locked to the back plate thereof substantially asset forth.

2. In wagon platform-gearing, a metallic head-block combining means forholding the The said truss-rods unite at their rear ends rear ends ofthe futchells and center bar and of holding and adjusting the tension ofthe truss-bars the latter consisting of two converging bars uniting atthe rear of the platform 1 1n a slngle bar which extends through saidhead-block substantially as set forth.

3. In a wagon platform-gearing two converging truss-rods united at theirrear ends in proximity to the head-block in combination with the saidhead-block means for securing their forward ends to the front cross-barand a nut for regulating their tension-bearing against the back plate ofthe said head-block substantially as set forth.

4. A metallic head-block provided with a top plate side plates f, backplate f bottom plate f cleats f a longitudinal groove X and a socket Xfor the pur ose set forth.

5. A pair of truss-rods unite at their rear ends and a head-blockreceiving the rod formed by their union in combination with means,bearing on the back plate of said head block, for locking saidtruss-rods and regulating their tension, the point ofunion of said rodsbeing in proximity to the head-block which is at the rear of theplatform substantially as and for the purpose set forth.

6. In wagon platform-gearing, the combination of the center bar A,futchells B B,

front cross-bar C, center cross-bar D, circlebar E, head-block F and thetruss-rods G G the front ends of which are fastened to the frontcross-bar C and the common rear end of which is passed through a socketin the top of the said head-block and secured thereto by a nut 90, whichbears against the back plate thereof the said head-block being at therear of the platform and the said rods uniting immediately in frontthereof, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
